What does CYL -0.50 and axis 165 only on right eye mean on eyeglasses rx?
What does CYL -0.50 and axis 165 only on right eye mean on eyeglasses rx?
I had difficulty seeing in my glasses and went again yesterday he modified the rx and under axis and cyl the left eye just says SPH and the right eye says CYL -0.50 and axis 165. The old rx that I was having difficulty seeing with had numbers for both eyes under CYL and axis. I wonder if that is why I couldn't see as well?

The cyl power means there is a bit of astigmatism, which is very common. The axis is just a direction to tell the lab where that cyl power is to be placed.
A small cyl power can sometimes be difficult to get used to. He removed it from the left lens apparently so that was probably causing your problems.
